BLIND R SHUTTER HINGE.

SPECIFICATION forming part'of Letters Patent No. 580,1 10, dated April6, 1897.

Application tiled November 2, 1895. Serial No. 567,690. (No modem To allwhomJ it may concern:

Be it known that l, ORANGE D. HUNTER, a citizen of the UnitedStates,residin g at Terryville, in the county of Litchfield and State ofConnecticut, have invented certainv new and useful Improvements in Blindor Shutter Hinges, of which the following is a specification.

My invention relates to improvements in blind or shutter hinges; and themain object of my improvement is to produce a simple and inexpensivehinge and one that will conveniently and eectually secure the blind indiiferent positions.

In the accompanying drawings, Figure lis a front elevation of my hinge.Fig. 2 is a rear elevation of the same. Fig. 3 is a horizontal sectionthereof on the line .fr x of Fig. 2. Fig. 4 is a detached end view ofthe plunger, and Fig. 5 is a detached side elevation showing the pintlemember of one part of my hinge.

A designates the pintle member of myhinge, the same being provided withany ordinary or desired means for securing it to the window casing orframe, as, for example, the shank 6. The pintle is provided with apointed upper end 7, which is preferably beveled off a little, the moston that side which is opposite the shank 6. The pintle is also providedwith three flattened faces 8, each of which has or may have a centraldepression, as shown in Figs. 3 and fl. l/Vhile I prefer to employ threesuch faces, an edective hinge may be produced with only two flattenedfaces on the pintle.

B designates the other member or portion of the hinge, which member isin the form of a strap-leaf having screw-hole perforations 9 forsecuring the same to the blind or shutter. It is also provided with aknuckle 10 and on its rear side with a spring and plunger chamber 1l,that opens into the pintle orifice through the knuckle. On the back sideof the knuckle there is arecess or notch 12,which opens toward thespring and plunger chamber. I also form a bridge 13 at the back of thehinge, having an opening to receive the small end of the securin gplunger li for guiding that end of said plunger. The main body of thesecuring-plunger is cylindrical, and at one end it is provided with ahead 15, preferably of disk form, and provided with a projection 16 atone edge, as shown, and the body of said plunger is surrounded by thespiral spring 17. The face of the plunger-head 16 is preferably providedwith a beveled ridge 1S to enter the central depressions in theflattened faces S of the pintle, but the faces ofthe plunger and pintlemay all be made plain, if desired.

In assembling the parts the body of the plunger is inserted in thespring, and then the two together are forced into the spring and plungersocket, the spring being compressed endwise at the time these parts areplaced in the socket. When the spring is released, it will bear againstthe bridge 13 at one end, while the other end will bear against the head15 and force said head against the knuckle until stopped by the edgeprojection 16 on the head 15 striking the bottom of the notch 12 in theknuckle, thereby preventing the head from entering the .pintleorifice inthe knuckle so far as to close it against the insertion of the pintle.At the same time the notch l2 is deep enough to insure a good bearing ofthe plunger on the flattened faces of the pintle. 'The memberA may becrowded into the knuckle of the part B by forcing the said part B downupon A. In so doing the beveled or pointed end of the pintle engages thehead of the plunger and forces it back out of the way of the pintleuntil the plungerhead l5 is opposite one of the flattened faces on thepintle, and then the spring presses said head l5 against the flattenedface of the pintle with all its force. After the leaf B is secured uponthe blind the plunger and spring cannot get out of place. As the blindor shutter is forced around on its hinges the plunger is pushed backagainst the spring until it passes the summit between two adjacentfiattened faces, and then the force of the spring throws the blindaround until the face of the plunger-head and one of the flattened facesof the pintle come squarely together and hold the blind in that positionuntil it is moved again by some outside force. The shank 6 of the pintleA will stand at a right angle to the blind when the blind isshut. Thethree flattened faces on the pintle enable the spring and plunger tohold the blind in its closed position or at right angles to the face ofthe IOO window-frame (its position then being the same as that shown inFigs. l, 2, and 3) or fully open clear hack against the side of thehouse. The blinds can readily be detached by merely lifting them and theleaves B off the pintles and can be hung again by simply placing theblind in position and forcing the knuckles of the leaves B upon thepintles. The central depressions in the flattened faces of the pintleand the ridge 1S on the plungerhead increase the life of the hinge andits holding power.

I claim as my inventionl. The herein-described hinge consisting` of thepintle member having holding-faces, the surface leaf B having a pintlereceiving knuckle and a covered but rearwardly open plunger-chamber, arearwardly open plungershank bearing at that end of said plungerchamberWhich is farthest from the knuckle, the plunger for pressing on theholding-faces of the pintle member, and the spring; the

rearwardly open chamber and plunger-shank l bearing being formed toreceive the plunger and spring by first inserting the plunger-head andspring endwise toward the knuckle-perforation and then pressing theshank end of the plunger and spring laterally into place, substantiallyas described.

2. In a hinge having the pintle portion with holding-faces and thecompanion surface leaf having a perforated knuckle and a coveredknuckle, substantially as described and for the purposedspecied. v
